Roller structure and method of using the same

Abstract

A roller structure and method of using the same are introduced. The roller structure includes a first sleeve having a mounting portion for mounting a roller portion and a first connection portion for mounting a carried object, wherein the roller portion is disposed at the mounting portion; and a positioning element disposed at the first sleeve and the roller portion to cause the roller portion to rotate relative to the mounting portion. The roller structure can be conveniently and quickly amounted on the carried object, roller frame or circuit board such that roller structure gets standardized and modularized to serve an industrial purpose and provides rollers rotatable in all directions and suitable for use in SMT (Surface Mount Technology) processes and automated assembly operation.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This non-provisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No(s). 103141361 filed in Taiwan, R.O.C. on Nov. 28, 2014, the entire contents of which are hereby incorporated by reference.FIELD OF TECHNOLOGY[0002]The present invention relates to roller structures and methods of using the same and, more particularly, to a roller structure and method of using the same, characterized in that the roller structure is mounted in a movable carried object and circuit board in a manner to allow the carried object and circuit board or any other related object to move by means of rollers.BACKGROUND[0003]A conventional movable object is exemplified by a sliding door of a chassis or cabinet, a drawer, a movable panel or a special circuit board. To reduce the friction between the movable components and a rail or another object, it is necessary to mount multiple rollers on the movable objects each; hence, the movable comp...

AI Technical Summary

Benefits of technology

[0006]It is an objective of the present invention to provide a roller structure applicable to movable objects, such as carried objects, so as to not only allow rollers to undergo modularized assembly and production but also achieve structural streamlining and cost cutting.

[0007]Another objective of the present invention is to provide a method of using the aforesaid roller structure such that rollers are fit for use with SMT (Surface Mount Technology) to thereby enhance assembly efficiency and cut assembly costs.

Problems solved by technology

For example, assembly-oriented structures dedicated to the conventional rollers and disposed on movable objects are usually intricate in terms of structure and their assembly procedure is difficult to carry out; as a result, the related assembly process or steps are so complicated as to compromise the production efficiency.

Also, the conventional roller structures are seldom suitable for forming modularized parts and components together with the other components, such as a shaft, and in consequence manufacturers have to cope with the processing process, the manufacturing process, and the assembly process on their own; as a result, modularized finished products of roller structures cannot be quickly mounted on the movable objects.

Furthermore, the conventional roller structures are unfit for use with SMT (Surface Mount Technology) and thus unlikely to be applicable to any automated assembly process in the course of any automated production process.
